Abstract: China's sport culture has shown a distinct trend of diversified development since the reform and opening up. It can be summarized as three main forms: sport catch-up culture, sport commercial culture and sport beneficial culture. Each of them contributes to sport development and social progress from different perspectives. With the acceleration of social transformation, the inherent shortcomings and limitations of those sport cultures have gradually revealed. Apparently, they are unable to provide support for the further development of sport in China. To curb the chronic epidemic diseases connected to inadequate physical activity and meet the needs of the people for a better life, it is imperative that sport and physical activities must be integrated into people's daily life in an all-round way. This requires us to construct life sport culture that closely links to the new social demands and the lifestyles of ordinary people on the basis of current sport culture.
